THOMAS E. MCDOWALL AND SAMUEL G. PERKINS, OF LONDON, ENGLANDGLAZIN'G-BAR.

I Specification of Letters Patent. Patented J 11116 12, 1917.

Application filed February 17, 1915. Serial No. 8,777.

To all whom it may concern:

Be it known that we, THOMAS REGINALD MCDOWALL and SAMUEL GREGORYPERKINS, subjects of the King of Great Britain, residing at let Uptallstreet, Myatts Park, London, and 27 Tw'illy street, Vandsworth, London,England, respectively, have invented new and useful Improvements inGlazin Ba1's, of which the following is a specification.

This invention relates to improvements connected with glazing bars orthe like and is more particularly for use in connection, with reinforcedconcrete bars or the like.

The object of our invention is to combine a lead or like flashing with aglazing bar or the like in such manner that it can be readily detachedfrom the said bar when necessary for making repairs thereto, or renewalof the glass, the said flashing being secured to the bar without theemployment of bolts and nuts or similar securing means, thus avoidingany slotting or holing of the flashing and the bar.

Referring to the drawings Figure 1 is a sectional perspective view ofone construction of this invention, showing the fixing strip in positionin the glazing bar, but the lead flashing has not yet been bent on tothe glass.

Fig. 2 is a similar view to Fig. 1, but illustrating the flashing inposition, as in use.

Fig. 3 is a perspective View of one form of holding strip.

Fig. 4 is a modification.

Referring first primarily to Figs. 1, 2 and 3, the reinforced concreteglazing bar 1 is formed of any suitable section and provided with anysuitable reinforcements, such as wires 2, the reinforcement beingcompletely embedded in the concrete so as to avoid any deleteriousaction thereon by the atmosphere. The glazing bar has the usualcondensation slots or grooves 3 therein, and shoulders 4; upon which theglass 5 rests.

A glazing bar constructed according to this invention is provided on itsupper surface with a longitudinal groove or slot 6 of a suitable depthand shape to receive the lead or other flashing 7 and a fixing strip orstrips 8. The section of the strip 8 depending upon the shape of thegroove or slot 6 wherein it is partly contained. When the groove or slot6 has parallel sides as seen in Figs. 1 and 2, the width of the slot isformed ust sufficient to receive the lead flashing and the strip 8 as adriving fit, so that when the strip has been forced or driven intoposition as seen in Fig. 1, it will eifectivelyretain the flashing 7within the slot 6. The strip 8 is made of metal, wood or other suitable,material and may be formed in one continuous length or in a series ofshort lengths as desired. IVhen the flashing 7 has been secured by thefixing strip in the position seen in Fig. 1, the flashing is bent overto contact with the glass 5, and thus the glass is firmly secured inposition without the employment of bolts, nuts, clips or other similarmeans, and avoiding also any drilling or screwing.

hen it is necessary to make repairs to the glass or flashing, the strip8 is removed from the slot 6 and the damaged or Worn parts repaired orremoved quickly and without resource to skilled labor.

In the modification illustrated by Fig. 5 of the drawings we employ azinc or other trough or channel 11 within the longitudinal slot 6,between the concrete and the lead flashing 7, the purpose of the saidtrough or channel 11 being to permit of a more ready insertion andremoval of the flashing when necessary, the trough or channel preventingthe roughened surface of the concrete contacting with the lead or otherflashing at that part of its area where it is forced or driven into theslot 6.

We do not limit our invention to the construction illustrated by theaccompanying drawings as obviously many other construetions could beeffected within the scope of the claims hereto appended.

We have described our invention more particularly with reference toconcrete or reinforced concrete glazing bars but it is obvious that itmay be applied to glazing bars made from wood or metal or other suitablematerials.

It will be obvious that our invention might with equal facility beapplied to purlins, ridges, hips or framings.

What we claim as our invention is 1. In a concrete or like plasticglazing or analogous bar having a groove therein the sides of which aresubstantially parallel to one another, the combination of a sheetmaterial flashing partly disposed within said groove and partly externalthereto said external part being adapted to secure the glazing lightupon the bar, and a substantially parallel sided fixing strip adapted tomaintain the said flashing on the bar, said strip being finallyintroduced into said groove and initially removed therefrom.

2. In a concrete or like plastic glazing or analogous bar having agroove therein the sides of Which are substantially parallel to oneanother, the combination of flashing of sheet material partly disposedWithin said groove said flashing comprising a strip of flexible metalhaving flanged external portions adapted to contact with the glazinglight and maintain same in position, and a i substantially parallelsided fixing strip adapted to maintain the said flashing on the bar,said strip being finally introduced into said groove and initiallyremoved therefrom.

3. In a concrete or like plastic glazing or analogous bar having agroove therein the sides of Which are substantially parallel to oneanother, the combination of a metal trough disposed Within said groovefor the purpose of facilitating the insertion and removal of theflashing, a flexible metal flashing partly disposed Within said troughand having flanged portions external to said trough to contact With theglazing light and maintain same in position, and a substantiallyparallel sided fixing strip adapted to maintain the said flashing on thebar, said strip being finally introduced into said Copies of this patentmay be obtained for five cents each, by addressing the Commissioner ofPatents,

Washington, D. G.
